In anticipation of her upcoming album Unbreakable, Janet Jackson kicked off her world tour in Vancouver on Monday night (Aug. 31).

Four years since her last tour, and seven since her last studio album, Ms. Jackson made a triumphant return to the stage at Rogers Arena.

Opening the night with an unreleased song (reportedly called "Burn It Up") that featured Missy Elliott rapping on video screen, the star made her way through a set that included two more new tracks, her latest single "No Sleeep" and a plethora of hits, from "Rhythm Nation" to "Scream."

(To mark her return, reports caught up with Jackson's longtime hairstylist to recall her most memorable 'dos.)

Jackson – who secretly married Qatari businessman Wissam Al Mana in 2012 – has been out of the spotlight the past few years but re-emerged earlier this summer.

“Thank you all so much for all your support from me and my entire family,” she told the sold-out crowd.

Janet’s “Unbreakable World Tour” makes it way throughout the U.S. and Canada through November before heading to Japan and returning to the U.S. for another leg in early 2016.
